AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
243 PM MDT WED JUN 20 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY...MOSTLY CLEAR OVERNIGHT. A THERMAL
TROUGH CURRENTLY OVER THE SIERRA NEVADA RANGE WILL MOVE NORTHEAST
INTO THE GREAT BASIN TOMORROW AND ENHANCE SOUTHEASTERLY SURFACE
WINDS ACROSS THE AREA. THIS COUPLED WITH SOUTHERLY FLOW ALOFT WILL
ALLOW TEMPERATURES THURSDAY AFTERNOON TO BE THE WARMEST OF THE
YEAR SO FAR...WITH HIGHS 10-15F ABOVE TODAY/S READINGS. STRONG
UPPER LEVEL LOW OFF THE PAC NW COAST WILL BEGIN TO PUSH INLAND
THURSDAY AFTERNOON. A SHORT WAVE EJECTING OFF OF THIS LOW WILL
INTERACT WITH A NARROW PLUME OF MOISTURE MOVING NORTH INTO EASTERN
OREGON TOMORROW NIGHT...AND A STRAY THUNDERSTORM OR TWO CANNOT BE
RULED OUT. THUS A RED FLAG WARNING FOR LIGHTNING HAS BEEN ISSUED
FOR THURSDAY EVENING IN THE VALE BLM. ON FRIDAY...INCREASING SHOWERS
AND THUNDERSTORMS AS THE LOW PRESSURE SYSTEM SLOWLY PUSHES INLAND.
ANOTHER DAY OF WARM TEMPERATURES IS EXPECTED FRIDAY AFTERNOON IN
IDAHO...WITH SLIGHTLY COOLER TEMPERATURES IN OREGON UNDER MOSTLY
CLOUDY SKIES.

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY...STRONG MODEL AGREEMENT
CONTINUES THROUGH THE EXTENDED. BEGINNING FRIDAY NIGHT WE SET UP UNDER
STRONG SOUTHWEST FLOW AS AN OMEGA BLOCK DEVELOPS OVER NORTH AMERICA...
WITH AN AREA OF DEEP LOW PRESSURE JUST OFF THE OREGON/WASHINGTON
COAST...ANOTHER LOW PRESSURE SYSTEM OVER THE GREAT LAKES REGION AND A
HIGH AMPLITUDE RIDGE BETWEEN THE TWO CENTERED OVER THE CENTRAL UNITED
STATES. THAT LEAVES US IN THE SOUTHWEST FLOW BETWEEN THE WESTERN
TROUGH AND CENTRAL RIDGE. MODERATE 500MB HEIGHTS WILL KEEP TEMPERATURES
VERY NEAR NORMAL THROUGH THE WEEKEND AND INTO NEXT WEEK. THE CHALLENGE
WILL BE IN TIMING ANY WEAK IMPULSES EMBEDDED IN THE SOUTHWEST FLOW THAT
COULD BRING AN INCREASED CHANCE OF PRECIP TO THE AREA. THE ATMOSPHERE
LOOKS TO DESTABILIZE EACH AFTERNOON AND EVENING DUE TO DAYTIME HEATING
AND STRONG UPPER LEVEL SUPPORT WHICH WILL BRING A CHANCE OF THUNDERSTORMS
MAINLY OVER SOUTHEAST OREGON AND THE HIGHER TERRAIN. ONLY MINOR FORECAST
CHANGES MADE AT THIS TIME.

.AVIATION...VFR UNDER MOSTLY CLEAR SKIES. SURFACE WINDS WILL BE LIGHT
OUT OF THE EAST OR SOUTHEAST IN MOST AREAS. WINDS ALOFT AT 10K FEET
